Overview of 4-102978-0-23 Rectangular Connectors - Headers, Male Pins
Rectangular connectors are standardized two-way or multi-way connectors used for joining electrical circuits.The 4-102978-0-23 is a type of rectangular connector, specifically a male header (also known as a male pin header or male connector). This device has an array of female contacts in a rectangular shape arranged in specific patterns, along with an array of male pins that fit into the slots of the female contacts.
Features
The 4-102978-0-23 male header features a durable plastic body, an array of 4 x 6 rectangular contacts and a 0.1 inch (2.54 mm) row-to-row centerline spacing. The device also features gold plated contacts for maximum performance, low-profile design, and a UL 94V-0 flammability rating. It is lead-free, RoHS compliant, and UL listed.
Uses for Male Headers
Male headers are commonly used in a variety of electrical applications, such as for transmitting signals between separate circuits. They are most commonly seen in PCBs and applications that require robust connectivity, such as robotics and automotive systems. Other common uses for male headers include connecting sensors and switches, as well as for joining power lines.
Working Principle of 4-102978-0-23
The working principle of a 4-102978-0-23 male header is as follows. The contacts in the connector are made up of a female contact (receptor) on one side and a male pin (connector) on the other. When the male pin is inserted into the female contact, an electrical connection is made between them. The connection is then maintained and consumes electrical current or signals through the contact. The contacts are typically held in place using screws, pins, or clips to form a secure connection. In addition, the contacts may be sealed with rubber or other materials to ensure that the connection is not affected by the corrosive effects of moisture and other elements.
Advantages of 4-102978-0-23 Connectors
The 4-102978-0-23 male header has numerous advantages over competing connectors or connector systems, such as those that are designed with single contact systems. The device offers a low-profile design and a high level of reliability due to its gold-plated contacts. It also offers superior performance as well as a secure connection. Additional features that make this device attractive include its compact size, light weight, and low cost.
Conclusion
The 4-102978-0-23 male header is a type of rectangular connector designed with an array of female contacts and a set of male pins. It is used in a variety of electrical applications, such as for connecting sensors and switches, as well as for joining power lines. The device offers a low-profile design, gold-plated contacts and superior performance. It is also cost-effective and features a light weight and compact size.
